Step-by-step explanation:
(a) In order to use the elimination method, multiply the second equation by 2.
It becomes 2x + 4y = 20.
Subtract that from the first equation: 3x + 4y = 12
3x + 4y - 2x - 4y = 12 - 20
x = -8
Put that back in the second equation: -8 + 2y = 10
2y = 18
y = 9
(b) In order to use the substitution method, subtract 2y from the second equation.
It becomes x + 2y - 2y = 10 - 2y
x = 10 - 2y
Substitute that into the first equation:
3(10 - 2y) + 4y = 12
30 - 6y + 4y = 12
30 - 2y = 12
2y = 18
y = 9
Put back into the equation for x:
x = 10 - 2(9)
= 10 - 18
= -8
You need to have the common denominator and once you do see how many times the 1/6cup will go into the 7/8cup which is 5
36 students does not watch regularly the programme.
Lets simplify the problem,
Total students = 48
Regular students 1//4*48
=> 12 students
Through Simple Subtraction method,
Irregular students = Total students - regular students
Irregular students = 48-12
=36
Hence 36 students does not watch regularly the programme.
